Problems solved by technology

Just because there is water in the bonding interface, the bonding strength between the paint film and the metal surface is greatly reduced and the hidden danger of corrosion from the inside of the paint is left

Abstract

The invention discloses a metal rust-proof dehumidizer, which is composed of 70-90% plant aliphatic derivant and 100% solvent through heating and stirring, wherein the plant aliphatic derivant is octadecyl primary amine acetate or hexadecyl primary amine acetate; the solvent is banana water or solvent oil; 1% dehumidizer and 100% oil priming paint are moulded evenly to paint normally without spraying.

Description

technical field [0001] The invention relates to an additive used in oily paints, in particular to a metal anti-corrosion desiccant used in oily paints. Background technique [0002] Metal corrosion seriously damages production and affects life. The use of paint is an effective means of anti-corrosion. The first primer is very important to achieve the ideal anti-corrosion purpose on the metal surface. In addition to the conditions such as high conjunctival strength of the coating itself and the addition of rust functional components, the bonding strength of the coating to the surface of the coated object determines the service life and anti-corrosion effect of the coating. At present, it is generally necessary to carry out shoveling and sandblasting treatment before painting and construction, and strive to improve the bonding strength of the primer interface. [0003] However, due to the presence of moisture in the air and on the metal surface, especially in a humid constr...
